Both men know what will happen after the first Phillie hits a home run at new Citizens Bank Park, which opens April 12 when the Phils play Cincinnati: A 47-foot-high, 36-foot-wide Liberty Bell, being designed and constructed by Capital, will ring into action.

The big bell will move back and forth, a clapper will slide from side to side, the gong of a bell will reverberate over the public address system, colored lights on the bell will come alive, fireworks will light up the sky.

"This will be the signature of the new ballpark, our icon," Giles said.

"My kids will start looking at me cross-eyed and say, "You did that, Dad?"' said Binder, who has five children and will take them all to the opener.

As for the rest of the fans at the park

"I think everyone will go out of their minds when they see it," Binder said.

The Liberty Bell can already be seen by people who drive by Capital's headquarters on Route 309.

"We have people pulling into the lot when we test it at night," Binder said.

Neither Giles nor Binder would disclose the cost of the Liberty Bell.

Over the years, Capital has developed a reputation as a sign company that builds specialty signs and related structures.

The company built the spilling crayon sculpture at the Crayola Factory in Easton, the giant steamship that springs into action whenever a Cincinnati Red hits a home run at the Great American Ballpark and the sculpture of the soup kids in front of Campbell's Field in Camden, N.J.

"We went to Capital and Mike Binder and they took it from an idea and made it work," Giles said. "We've had dealings with them over the years at Veterans Stadium and they're one of the leaders in this business."

Andy Bertucci, executive director of the United States Sign Council, said there are about 30,000 companies in this country that construct signs. It's a $6 billion-a-year industry, Bertucci said.

According to Binder, Giles came to him with an idea that was "unbuildable," a huge glass wall on which a bell made of neon lights moved back and forth."

"You can't get glass that big," Binder said.

Instead, Binder came up with a different concept for the bell and turned it over to Giovanni Lunelli, the company's director of art and architecture.

"There were many difficulties at first," Lunelli said.

One was moving the 6,000-pound bell and clapper from side to side. The solution was a large hydraulic system.

The bell will move 9 feet to the side, back to center, then 9 feet to the other side, while the clapper moves in the opposite direction of the bell. The movement and lights will be controlled by the same person who works the park's high-tech scoreboard.

To keep the weight down, the bell's frame is made of aluminum. It is outlined with red, white and blue strands of neon light and has a series of 21 stars on it that are highlighted with some of the 2,800 light-emitting diodes on the bell.

"To make the stars really bright, we used the same LEDs police cars use; they're the brightest ones out there," Binder said.

The bell is being built in detachable sections. After it's finished and has been tested, it will be disassembled, trucked to the stadium and reassembled at the top of a 100-foot-high steel frame above the bleachers in right-center field.

The bell is one of many items Capital is making for the new park.

On Friday, the Citizens Bank Park sign -- bright-green, 12-foot-tall letters -- that will be over the entrance was loaded onto trucks for shipping to south Philadelphia. Inside the factory, employees were busy building the 25-foot-high "P" and the other seven letters that will be part of the Phillies sign over the scoreboard.

Although Binder said he knew the Liberty Bell design would work, he was wowed during the first test.

"You wonder how well it will work, if your vision is realized," he said. "This exceeded my vision by 100 times."
